Q6Thrice a number when decreased by one fourth gives 11.Find the number.​

Answer 1

Step-by-step explanation:

Ans 3 ) Let the number be x

x /3 + 5 = 8

x/ 3 + 15/3 = 8

x + 15 = 8 × 3

x + 15 = 24

x = 24 - 15

x = 9

Ans 4) let the number be x

6x - 5 = 7

6x = 7 + 5

6x = 12

x = 12 /6

x = 2

Ans 5) let the number be x

x + 5 = 35

x = 35- 5

x = 30

Ans 6) let the number be x

3x - 1/ 4 = 11

( 12x - 1) / 4 = 11

12x - 1 = 11 ×4

12x - 1 = 44

12x = 44 + 1

12x = 45

x = 45/ 12

x. = 15/ 4

Answer 2

Question 3

Let the number be x

1/3*X +5 = 8

1/3*X = 8-5=3

X= 3÷1/3

X=3*3

9

Thus number is 9

Question 4

Let the number be x

According to the question

6X-5=7

6x = 7+5=12

X= 12/6

2

Thus the number is 2

Question 5

Let the number be X

According to the question

X+5=35

X=35-5

30

Thus, the number is 30

Question 6

the question is not clear of it is asking 1/4 th of the number or simply 1/4 but as far as I understand it is

let the number be x

According to the question

1/4*X - 3x=11

X/4 - 3x/1 = 11

X/4 - 12x/4= 11

-11x/4=11

X= 11 *4/ -11

=44/-11

= -4

Number is -4
